So with the usual delay ... finally our review of the bokeh monster ...

next PZ lens test report: Sony FE 100mm f/2.8 STF GM OSS - stoppingdown - 08-21-2017
Quote:I'd rather state that the lens is aligned to still life and nature photography where you are often facing very busy and contrasty fore- and backgrounds and this STF lens can kill hard edges like no other.
I can't comment about wedding, as I never do that kind of photography, but I do agree that the lens would be excellent for still life and nature.
Quote:I'd even state that it can substitute a macro lens down to a magnification of 1:4 although that may not be sufficient for critters at least.
It would be interesting to see whether somebody tests it with a close-up lens or an extension tube.
Quote:Interestingly Sony implemented a dedicated aperture ring. Some users may still prefer this but it feels a little bit like a gimmick these days.
I'm one of those users who'd appreciate that...
Quote:The camera will always display the T-value which feels a little unfortunate because such a lens is primarily about the depth-of-field rather than the effective speed so it's a little difficult to estimate the effect on the depth-of-field when stopping down.
Shouldn't be really hard for Sony to publish a firmware update, at least for the most recent A7*, and offer an option to switch between f/stop and T-value in the EVF - or even show both.

It would have been nice if the lens could focus a bit closer (to 1:3 or even 1:2), but it is a very nice lens, for a steep price.

Does the T stop impact diffraction or does diffraction set in based off of the f stop ?

Also pity the lens isn't APO; the bokeh is creamy but with lots of green borders.

A cool lens if very specialized. Not the one I'd probably want to get, but fun to read the review nevertheless.

Diffraction is related to the f-stops. T-stops are about the transmission only.

Smooth as the proverbial baby's botty!
I would like to see the lens formula (elements in cutaway with diaphragm)!
